granted to Optionees under the Plan and each Option Agreement (which need not be
identical with the terms of other Options and Option Agreements) and, with the
consent of the Optionee, to modify or amend an outstanding Option or Option
Agreement; (vii) to accelerate the exercise date of any Option; (viii) to
determine whether any Optionee will be required to execute a stock repurchase

<PAGE>

pursuant to Options or agreements relating to the grant or exercise thereof; and
(xi) to make such other determinations and establish such other procedures as it
deems necessary or advisable for the administration of the Plan. Notwithstanding
anything else herein, the Committee shall not have the authority to adjust or
amend the exercise price of any Options previously awarded to any Optionee,
whether through amendment, cancellation, replacement grant or other means.

         c.       All decisions, determinations and interpretations of the
Committee shall be final and binding on all Optionees and any other holders of
any Options granted under the Plan.

         d.       The Committee shall keep minutes of its meetings and of the
actions taken by it without a meeting. A majority of the Committee shall
constitute a quorum, and the actions of a majority at a meeting, including a
telephone meeting, at which a quorum is present, or acts approved in writing by
a majority of the members of the Committee without a meeting, shall constitute
acts of the Committee.

         e.       The Company shall pay all original issue and transfer taxes
with respect to the grant of Options and/or the issue and transfer of Shares
pursuant to the exercise thereof, and all other fees and expenses necessarily
incurred by the Company in connection therewith; provided, however, that the
person exercising an Option shall be responsible for all payroll, withholding,
income and other taxes incurred by such person in respect of the exercise of an
Option or transfer of Shares.

5.       Eligibility.

         Non-Statutory Stock Options may be granted under the Plan to Employees
and Non-Employee Directors; Incentive Stock Options may be granted under the
Plan only to Employees. An Employee or Non-Employee Director who has been
granted an Option may, if he or she is otherwise eligible, be granted additional
Options.

6.       Non-Employee Directors.

         Notwithstanding the powers set forth in Section 4(b) of the Plan, the
Committee shall have no power to determine eligibility for grants of
Non-Statutory Stock Options or to increase the number of Shares for which
Non-Statutory Stock Options may be granted or the timing or exercise price of
Non-Statutory Stock Options granted to any Non-Employee Director.

         All Non-Employee Directors of the Company are granted automatically a
Non-Statutory Stock Option to purchase up to 10,000 Shares, and a Non-Employee
Director elected to serve as Chairman of the Board is granted automatically a
Non-Statutory Stock Option to purchase up to an additional 10,000 Shares: (1) as
of the date such person is elected (or reelected) to serve as a Non-Employee
Director and/or as Chairman, respectively, and (2) as of the first and second
anniversary of such election (or reelection) provided that the Optionee is
serving as of such first or second anniversary during the respective
directorship term as a Non-Employee Director. Any such Shares shall vest and
become exercisable, cumulatively, in 12 equal monthly installments commencing on

                                     - 4 -
<PAGE>

the last business day of the month of grant; provided that if an Optionee ceases
to serve as a Non-Employee Director during any month, the Option shall cease to
vest and become exercisable with respect to any subsequent month(s).

         If the election of a Non-Employee Director or Chairman occurs prior to
an annual stockholders' meeting, the Non-Employee Director shall receive a pro
rata option grant (or, in the case of Chairman, an additional pro rata option
grant) in connection with his or her election, and the related Shares shall vest
and become exercisable, cumulatively, in equal monthly installments.

         The Non-Employee Director appointed by the Board as the Lead
Independent Director shall be granted automatically a Non-Statutory Stock Option
to purchase up to 2,000 Shares as of the date such person is appointed or
reappointed to serve as Lead Independent Director. Any such Non-Statutory
Options shall vest and become exercisable cumulatively, in 12 equal monthly
installments commencing on the last business day of the month of grant; provided
that if the Optionee ceases to serve as a Lead Independent Director during any
month, the option shall cease to vest and become exercisable with respect to any
subsequent month(s). All other terms and conditions in this Plan regarding
Options granted automatically to Non-Employee Directors shall also apply to the
above-referenced Options to be granted to the Lead Independent Director.

         If an Optionee ceases to serve as a Non-Employee Director for any
reason, he or she may thereafter exercise his or her Option, to the extent he or
she was entitled to do so at the date of such cessation, at any time before the
earlier of (a) the fifth anniversary of the cessation date and (b) the date on
which the respective Option would have expired if the Optionee had not ceased to
serve as a Non-Employee Director. The post cessation exercise period of an
Option granted to a Non-Employee Director, as set forth in the immediately
preceding sentence, shall apply to Options previously granted automatically to
the Non-Employee Directors hereunder and to Options granted automatically to
Non-Employee Directors hereunder in the future.

To the extent that an Optionee who is a former Non-Employee Director does not
exercise his or her Options (which he or she was entitled to exercise) within
the applicable time period specified herein, the Option shall terminate. The
consideration to be paid for the Shares to be issued upon exercise of an option
by a Non-Employee Director shall consist of (a) cash or check or (b) subject to
approval by the Committee, cash, check, broker's commitment to pay, or Common
Stock held by the Optionee for at least six months, or some combination thereof.

7.       Terms and Conditions of Options.

         Options granted pursuant to the Plan by the Committee shall be either
Incentive Stock Options or Non-Statutory Stock Options and shall be evidenced by
an Option Agreement providing, in addition to such other terms as the Committee
may deem advisable, the following terms and conditions:

         a.       Time of Granting Options. The date of grant of an Option
shall, except in the case of Non-Employee Directors, be the date on which the
Committee makes the determination granting such Option. Notice of the
determination shall be given to each Optionee within a reasonable time after the
date of such grant.

                                     - 5 -
<PAGE>

         b.       Number of Shares. Each Option Agreement shall state the number
of Shares to which it pertains and whether such Option is intended to constitute
an Incentive Stock Option or a Non-Statutory Stock Option. The maximum number of
Shares which may be subject to Options granted under the Plan during any
calendar year to any Optionee is 100,000 Shares. If an Option held by an
Employee of the Company is canceled, the canceled Option shall continue to be
counted against the maximum number of Shares for which Options may be granted to
such Employee and any replacement Option granted to such Employee shall also
count against such limit.

         c.       Exercise Price. The exercise price per Share for the Shares to
be issued pursuant to the exercise of an Option shall be such price as is
determined by the Committee; provided, however, that with respect to both
Non-Statutory Stock Options and Incentive Stock Options such price shall in no
event be less than 100% of the Fair Market Value per Share on the date of grant,
except that the Committee may specifically provide that the exercise price of an
Option may be higher or lower in the case of an Option granted to employees of a
company acquired by the Company in assumption and substitution of options held
by such employees at the time such company is acquired.

                  In the case of an Incentive Stock Option granted to an
Employee who, at the time the Incentive Stock Option is granted, owns or is
deemed to own (by reason of the attribution rules applicable under Section
424(d) of the Code) stock possessing more than 10% of the combined voting power
of all classes of stock of the Company, the exercise price per Share shall be no
less than 110% of the Fair Market Value per Share on the date of grant.

         d.       Medium and Time of Payment. Except in the case of Non-Employee
Directors, which shall be governed by Section 6, the consideration to be paid
for the Shares to be issued upon exercise of an Option and to be paid to satisfy
any withholding tax obligation incident thereto, including the method of
payment, shall be determined by the Committee and, subject to approval by the
Committee, may consist entirely or in any combination of cash, check, a
commitment to pay by a broker or Shares held by the Optionee or issuable upon
exercise of the Option, or such other consideration and method of payment
permitted under any laws to which the Company is subject. In the case of an
Incentive Stock Option, such provision shall be determined on the date of the
grant.

         e.       Term of Options. The term of an Incentive Stock Option may be
up to 10 years from the date of grant thereof; provided, however, that the term
of an Incentive Stock Option granted to an Employee who, at the time the
Incentive Stock Option is granted, owns or is deemed to own (by reason of the
attribution rules of Section 424(d) of the Code) stock possessing more than 10%
of the total combined voting power of all classes of stock of the Company, shall
be five years from the date of grant thereof or such shorter term as may be
provided in the Option.

                                     - 6 -
<PAGE>

                  The term of a Non-Statutory Stock Option, in the case of an
Employee, may be up to 10 years from the date such Employee first becomes vested
in any portion of an Option award; and in the case of Non-Employee Director,
shall be 10 years from the date of grant thereof.

                  The term of any Option, other than an Option awarded to a
Non-Employee Director, may be less than the maximum term provided for herein as
specified by the Committee upon grant of the Option and as set forth therein.

         f.       Maximum Amount of Incentive Stock Options. To the extent that
the aggregate Fair Market Value (determined at the time an Incentive Stock
Option is granted) of the Shares with respect to which Incentive Stock Options
are exercisable for the first time by an Optionee during any calendar year under
all incentive stock option plans of the Company exceeds $100,000, the Options in
excess of such limit shall be treated as Non-Statutory Stock Options.

8.       Exercise of Option.

         a.       In General. Any Option granted hereunder to an Employee shall
be exercisable at such times and under such conditions as may be determined by
the Committee and as shall be permissible under the terms of the Plan, including
any performance criteria with respect to the Company and/or the Optionee as may
be determined by the Committee. Any Option granted hereunder to a Non-Employee
Director shall be exercisable at such times and under such conditions as set
forth in Section 6 of the Plan.

                  An Option may be exercised in accordance with the provisions
of the Plan as to all or any portion of the Shares then exercisable under an
Option from time to time during the term of the Option. However, an Option may
not be exercised for a fraction of a Share.

         b.       Procedure. An Option shall be deemed to be exercised when
written notice of such exercise has been given to the Company at its principal
business office in accordance with the terms of the Option Agreement by the
person entitled to exercise the Option and full payment for the Shares with
respect to which the Option is exercised has been received by the Company,
accompanied by any other agreements required by the terms of the Plan and/or
Option Agreement or as required by the Committee and payment by the Optionee of
all payroll, withholding or income taxes incurred in connection with such Option
exercise (or arrangements for the collection or payment of such tax satisfactory
to the Committee are made). Full payment may consist of such consideration and
method of payment allowable under Section 7(d) of the Plan.

         c.       Decrease in Available Shares. Exercise of an Option in any
manner shall result in a decrease in the number of Shares which thereafter may
be available, both for purposes of the Plan and for sale under the Option, by
the number of Shares as to which the Option is exercised.

         d.       Exercise of Stockholder Rights. Until the Option is properly
exercised in accordance with the terms of this section, no right to vote or
receive dividends or any other rights as a stockholder shall exist with respect

                                     - 7 -
<PAGE>

to the Optioned Stock. No adjustment shall be made for a dividend or other right
for which the record date is prior to the date the Option is exercised, except
as provided in Section 11 of the Plan.

         e.       Termination of Eligibility. If an Optionee ceases to serve as
an Employee for any reason other than death or permanent and total disability
(within the meaning of Section 22(e)(3) of the Code) and thereby terminates his
or her Continuous Status as an Employee he or she may, but only within one
month, or such other period of time not exceeding three months in the case of an
Incentive Stock Option (or in the case of an Optionee subject to Rule 16b-3 of
the Securities Exchange Act of 1934, as amended, the greater of six months from
the date of the Option award or three months from the date of termination of
employment) or six months in the case of a Non-Statutory Stock Option, in each
case as is determined by the Committee, following the date he or she ceases his
or her Continuous Status as an Employee (subject to any earlier termination of
the Option as provided by its terms), exercise his or her Option to the extent
that he or she was entitled to exercise it at the date of such termination. To
the extent that he or she was not entitled to exercise the Option at the date of
such termination, or if he or she does not exercise such Option (which he or she
was entitled to exercise) within the time specified herein, the Option shall
terminate. Notwithstanding anything to the contrary herein, the Committee may at
any time and from time to time prior to the termination of a Non-Statutory Stock
Option, with the consent of the Optionee, extend the period of time during which
the Optionee may exercise his or her Non-Statutory Stock Option following the
date he or she ceases his or her Continuous Status as an Employee; provided,
however, that the maximum period of time during which a Non-Statutory Stock
Option shall be exercisable following the date on which an Optionee terminates
his or her Continuous Status as an Employee shall not exceed an aggregate of six
months, that the Non-Statutory Stock Option shall not be, or as a result of such
extension become, exercisable after the expiration of the term of such Option as
set forth in the Option Agreement and, notwithstanding any extension of time
during which the Non-Statutory Stock Option may be exercised, that such Option,
unless otherwise amended by the Committee, shall only be exercisable to the
extent the Optionee was entitled to exercise it on the date he or she ceased his
or her Continuous Status as an Employee.

         f.       Death or Disability Of Optionee. If an Optionee's Continuous
Status as an Employee ceases due to death or permanent and total disability
(within the meaning of Section 22(e)(3) of the Code) of the Optionee, the Option
may be exercised within six months (or such other period of time not exceeding
one year as is determined by the Committee) following the date of death or
termination of employment due to permanent or total disability (subject to any
earlier termination of the Option as provided by its terms), by the Optionee in
the case of permanent or total disability, or in the case of death by the
Optionee's estate or by a person who acquired the right to exercise the Option

                                     - 8 -
<PAGE>

by bequest or inheritance, but in any case (unless otherwise determined by the
Committee) only to the extent the Optionee was entitled to exercise the Option
at the date of his or her termination of employment by death or permanent and
total disability. To the extent that he or she was not entitled to exercise such
Option at the date of his or her termination of employment by death or permanent
and total disability, or if he or she does not exercise such Option (which he or
she was entitled to exercise) within the time specified herein, the Option shall
terminate.

         g.       Expiration of Option. Notwithstanding any provision in the
Plan, including but not limited to the provisions set forth in Sections 8(e) and
8(f), an Option may not be exercised, under any circumstances, after the
expiration of its term.

         h.       Conditions on Exercise and Issuance. As soon as practicable
after any proper exercise of an Option in accordance with the provisions of the
Plan, the Company shall deliver to the Optionee at the principal executive
office of the Company or such other place as shall be mutually agreed upon
between the Company and the Optionee, a certificate or certificates representing
the Shares for which the Option shall have been exercised. The time of issuance
and delivery of the certificate or certificates representing the Shares for
which the Option shall have been exercised may be postponed by the Company for
such period as may be required by the Company, with reasonable diligence, to
comply with any law or regulation applicable to the issuance or delivery of such
Shares.

                  Options granted under the Plan are conditioned upon the
Company obtaining any required permit or order from appropriate governmental
agencies, authorizing the Company to issue such Options and Shares issuable upon
exercise thereof. Shares shall not be issued pursuant to the exercise of an
Option unless the exercise of such Option and the issuance and delivery of such
Shares pursuant thereto shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Securities Exchange Act of 1934, as amended, applicable state law, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange
upon which the Shares may then be listed, and may be further subject to the
approval of counsel for the Company with respect to such compliance.

         i.       Withholding or Deduction for Taxes. The grant of Options
hereunder and the issuance of Shares pursuant to the exercise thereof is
conditioned upon the Company's reservation of the right to withhold, in
accordance with any applicable law, from any compensation or other amounts
payable to the Optionee any taxes required to be withheld under Federal, state
or local law as a result of the grant or exercise of such Option or the sale of
the Shares issued upon exercise thereof. To the extent that compensation and
other amounts, if any, payable to the Optionee are insufficient to pay any taxes
required to be so withheld, the Company may, in its sole discretion, require the
Optionee, as a condition of the exercise of an Option, to pay in cash to the

                                     - 9 -
<PAGE>

Company an amount sufficient to cover such tax liability or otherwise to make
adequate provision for the delivery to the Company of cash necessary to satisfy
the Company's withholding obligations under Federal and state law.

9.       Non-transferability of Options.

         Options granted under the Plan may not be sold, pledged, assigned,
hypothecated, gifted, transferred or disposed of in any manner, either
voluntarily or involuntarily by operation of law, other than by will or by the
laws of descent or distribution or, if permitted of Options granted under Rule
16b-3, transfers between spouses incident to a divorce.

10.      Holding Period.

         In the case of officers and directors of the Company, at least six
months must elapse from the date of grant of the Option to the date of
disposition of the underlying Shares.

11.      Adjustment Upon Change in Corporate Structure.

         a.       Subject to any required action by the stockholders of the
Company, the number of Shares covered by each outstanding Option, and the number
of Shares which have been authorized for issuance under the Plan but as to which
no Options have yet been granted or which have been returned to the Plan upon
cancellation or expiration of an Option, as well as the exercise or purchase
price per Share covered by each such outstanding Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from a stock split or combination or the payment of a stock
dividend (but only on the Common Stock) or any other increase or decrease in the
number of issued Shares effected without receipt of consideration by the Company
(other than stock awards to Employees or directors); provided, however, that the
conversion of any convertible securities of the Company shall not be deemed to
have been effected without the receipt of consideration. Such adjustment shall
be made by the Committee, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of Shares subject to the Plan or an
Option.

         b.       In the event of the proposed dissolution or liquidation of the
Company, or in the event of a proposed sale of all or substantially all of the
assets of the Company (other than in the ordinary course of business), or the
merger or consolidation of the Company with or into another corporation, as a
result of which the Company is not the surviving and controlling corporation,
the Board of Directors shall (i) make provision for the assumption of all
outstanding options by the successor corporation or (ii) declare that any Option
shall terminate as of a date fixed by the Board of Directors which is at least
30 days after the notice thereof to the Optionee and shall give each Optionee
the right to exercise his or her Option as to all or any part of the Optioned
Stock, including Shares as to which the Option would not otherwise be
exercisable provided such exercise does not violate Section 8(e) of the Plan.

                                     - 10 -

         c.       No fractional shares of Common Stock shall be issuable on
account of any action aforesaid, and the aggregate number of shares into which
Shares then covered by the Option, when changed as the result of such action,
shall be reduced to the largest number of whole shares resulting from such
action, unless the Board of Directors, in its sole discretion, shall determine
to issue scrip certificates in respect to any fractional shares, which scrip
certificates, in such event shall be in a form and have such terms and
conditions as the Board of Directors in its discretion shall prescribe.

12.      Stockholder Approval.

         Effectiveness of the Plan shall be subject to approval by the
stockholders of the Company within 12 months before or after the date the Plan
is adopted; provided, however, that Options may be granted pursuant to the Plan
subject to subsequent approval of the Plan by such stockholders. Stockholder
approval shall be obtained by the affirmative votes of the holders of a majority
of voting Shares present or represented and entitled to vote at a meeting of
stockholders duly held in accordance with the laws of the state of Delaware.

13.      Amendment and Termination of the Plan.

         a.       Amendment and Termination. Except as provided in Section 13(b)
of the Plan, the Committee may amend or terminate the Plan from time to time in
such respects as the Committee may deem advisable and shall make any amendments
which may be required so that Options intended to be Incentive Stock Options
shall at all times continue to be Incentive Stock Options for the purpose of
Section 422 of the Code; provided, however, that without approval of the holders
of a majority of the voting Shares present or represented and entitled to vote
at a valid meeting of stockholders, no such revision or amendment shall be made
that affects the ability of Options thereafter granted under the Plan to satisfy
Rule 16b-3.

         b.       Effect of Amendment or Termination. Except as otherwise
provided in Section 11 of the Plan, any amendment or termination of the Plan
shall not affect Options already granted and such Options shall remain in full
force and effect as if the Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Company, which agreement
must be in writing and signed by the Optionee and the Company. Notwithstanding
anything to the contrary herein, this 1996 Stock Option Plan shall not adversely
affect, unless mutually agreed in writing by the Company and an Optionee, the
terms and provisions of any Option granted prior to the date the Plan was
approved by stockholders as provided in Section 12 of the Plan.

14.      Indemnification.

         No member of the Committee or of the Board of Directors shall be liable
for any act or action taken, whether of commission or omission, except in
circumstances involving willful misconduct, or for any act or action taken,
whether of commission or omission, by any other member or by any officer, agent,

                                     - 11 -
<PAGE>

or Employee. In addition to such other rights of indemnification they may have
as members of the Board of Directors, or as members of the Committee, the
Committee shall be indemnified by the Company against reasonable expenses,
including attorneys' fees actually and necessarily incurred in connection with
the defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken, by commission or omission, in connection with the Plan or any Option
taken thereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by
the Company) or paid by them in satisfaction of a judgment in any action, suit
or proceeding, except in relation to matters as to which it shall be adjudged in
such action, suit or proceeding that such Committee member is liable for willful
misconduct in the performance of his or her duties; provided that within 60 days
after institution of any such action, suit or proceeding, a Committee member
shall in writing offer the Company the opportunity, at its own expense, to
handle and defend the same.

15.      General Provisions.

         a.       Other Plans. Nothing contained in the Plan shall prohibit the
Company from establishing additional incentive compensation arrangements.

         b.       No Enlargement of Rights. Neither the Plan, nor the granting
of Shares, nor any other action taken pursuant to the Plan shall constitute or
be evidence of any agreement or understanding, express or implied, that the
Company will retain an Employee or a Non-Employee Director for any period of
time, or at any particular rate of compensation. Nothing in the Plan shall be
deemed to limit or affect the right of the Company or any such corporations to
discharge any Employee thereof at any time for any reason or no reason. Nothing
in the Plan shall in any way limit or affect the right of the Board of Directors
or the stockholders of the Company to remove any Non-Employee Director or
otherwise terminate his or her service as a director of the Company.

                  No Employee or Non-Employee Director shall have any right to
or interest in Options authorized hereunder prior to the grant thereof to such
eligible person, and upon such grant he or she shall have only such rights and
interests as are expressly provided herein and in the related Option Agreement,
subject, however, to all applicable provisions of the Company's Certificate of
Incorporation, as the same may be amended from time to time.

         c.       Notice. Any notice to be given to the Company pursuant to the
provisions of the Plan shall be addressed to the Company in care of its
Secretary (or such other person as the Company may designate from time to time)
at its principal office, and any notice to be given to an Optionee whom an
Option is granted hereunder shall be delivered personally or addressed to him or
her at the address given beneath his or her signature on his or her Stock Option
Agreement, or at such other address as such Optionee or his or her transferee
(upon the transfer of the Optioned Stock) may hereafter designate in writing to

                                     - 12 -
<PAGE>

the Company. Any such notice shall be deemed duly given when enclosed in a
properly sealed envelope or wrapper addressed as aforesaid, registered or
certified, and actually received by the Company. It shall be the obligation of
each Optionee holding Shares purchased upon exercise of an Option to provide the
Secretary of the Company, by letter mailed as provided hereinabove, with written
notice of his or her direct mailing address.

         d.       Applicable Law. To the extent that Federal laws do not
otherwise control, the Plan shall be governed by and construed in accordance
with the laws of the State of Delaware, without regard to the conflict of laws
rules thereof.

         e.       Incentive Stock Options. The Company shall not be liable to an
Optionee or other person if it is determined for any reason by the Internal
Revenue Service or any court having jurisdiction that any Incentive Stock
Options are not incentive stock options as defined in Section 422 of the Code.

         f.       Information to Optionees. The Company shall provide without
charge to each Optionee copies of such annual and periodic reports as are
provided by the Company to its stockholders generally.

         g.       Availability of Plan. A copy of the Plan shall be delivered to
the Secretary of the Company and shall be shown by him or her to any eligible
person making reasonable inquiry concerning it.

         h.       Severability. In the event that any provision of the Plan is
found to be invalid or otherwise unenforceable under any applicable law, such
invalidity or unenforceability shall not be construed as rendering any other
provisions contained herein as invalid or unenforceable, and all such other
provisions shall be given full force and effect to the same extent as though the
invalid or unenforceable provision was not contained herein.

16.      Effective Date and Term of Plan.

         The Plan shall become effective upon stockholder approval as provided
in Section 12 of the Plan. The Plan shall continue in effect for a term of ten
years unless sooner terminated under Section 13 of the Plan.
